A handset is assigned the following numbers
after it is registered with the base station:
– Receiving numbers: all phone numbers
assigned to the phone (fixed network and
VoIP).
– Sending numbers: the fixed network
number and the VoIP phone number that
you entered at the start of the phone con-
figuration.

This will display the names of all registered
handsets, and a list for each handset with
the phone numbers that are configured
and activated for the phone. The connec-

column. The fixed network connection is
always at the end of the list.
¤
Define a VoIP phone number as the
sending number for each handset. To

phone number in the

number. This assignment cannot be deacti-
vated. This guarantees that emergency
numbers can be dialled from every handset.

ing numbers. To do this, click on the

to any of the handsets, calls to all connec-
tions will be signalled on all handsets.

Setting DTMF signalling for VoIP

DTMF signalling is required, for example,
for playing and controlling some network
mailboxes via key codes (digits).
For VoIP specify how key codes are to be
converted and sent as DTMF signals: as
audible information in the voice channel
or as a "SIP Info" message.
Ask your VoIP provider which type of
DTMF transmission it supports.
